Hale’s new Model ESP Priming System provides the ultimate in fast priming, high vacuum performance and reliability without the use of a lubricant.
Technologically advanced and environmentally safe, the Model ESP is self-lubricating. There is no oil tank to check; no oil is expelled to the ground. The Model ESP is a semi-automatic priming system with a single action control valve, which simultaneously activates the entire system, ensuring fast, consistent air evacuation. Hale’s electric rotary vane-type positive displacement primer operates with 12-volt or 24-volt DC power.
